\ BOTTLE car.

To all whom it may concern:

Be it known that I, Svsxn HAxsEx,'a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented a new and useful Improvement in Bottle Caps; and I dohereby declare the following, when takenin connection with theaccompanying drawings and the characters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawings constitute. part of this application, and represent, in

Fig. 1 an inside. view of a bottle cap constructed in accordance with myinvention. Fig. 2 a sectional view on the line 2-2 of Fig. 1. F

Fig. 3 aperspective view of the metal Fig. 4 a perspective view of thecork disk detached. V p v This invention relates to an improvement inbottle caps, and particularly to caps which are formed from metal andadapted to be clamped over the neck of a bottle to Securely close thesame. These stoppers generally include a disk of cork, so that a tightclosure is provided for the bottle, but in preparing these. corks foruse, various chemicals are employed which, in some cases, as forinstance in bottled waters, are

liable to aflect the contents. To avoid this tached to the cork by anadhesive material, but if the disk becomes accidentally removed, theadhesive material simply adds .one element of contamination.

Specification of Letters Patent.

Patented July 18, 1922.

Application filed September 13, 1921. Serial No. 500,408.

7 The object of this invention is to provide ametal covering for theexposed portion of the cork, and the invention consists in the 4construction as hereinafter described and particularly recited in theclaim.

In carrying out my invention, I employ a metal bottle cap 5 of usualconstruction,

which is adapted to be clamped over the 4 neck of a bottle. In this capis a ring'6 of cork, into the center of which I insert a cup 7 of metalcorresponding in depth to the thickness of the cork, so as to bear onthe inner face of the cap, and the cup is provided with a flange 8overlapping the edge of the cork, but'smaller in diameter than thediameter of the cork, so that the cork will bear upon the edge of thebottle to which thecap is applied. These cups are formed from very thinmetal struck'up in automatic machines and readily applied to the corks,and when applied are not liable to become accidently detached, and coverthe exposed portion of the corks, so that the 6 contents of the bottlecannotcome in contact therewith.

I claim: The comblnation of a metal bottle cap with a ring of corkinserted therein, and a metal cup inserted into the center of the corkto bear against the inner face of the capand formed with a flangeoverlapping the inner edge of the faceof the cork.
